Isaac said: "I've seen on the Yamaha owners manuals (on line they are available)2 differenet tuning curves for the CP 70 and CP 80 (if memory serves) . possibli the scaling changed also with different generations of these beasts. Joe did you use buckskin on the hammers, I can't see the artificial leather sold separately, in fact only "Hammer assembly" is listed in my parts manual for CP 70-80. The leather seem to be tense on the hammers. I wonder also if it can be surfaced, needled, etc. Greetings. ------------------------------------ PianoTech Isaac OLEG Isaac, Regarding the two "tuning curves" via Yamaha...it's possible they changed the scale, but I don't think the "tuning curves" has anything to do with that. Well, maybe. Who knows what evil lurks there!<G> I did order the hammer "leather" separately. Matter of fact I still have some, (probably enough for another set. I usually order things in sets of two.) As for voicing of that stuff....as I remember I tried and found that it was a futile effort! And, yes, the hammer covering is Tight, because the synthetic buckskin comes with it's own adhesive back!<G> Just checked my stock and the stuff is still very supple and I have enough for several sets of hammers! As I recall, I ordered a bunch of the stuff because I was going to use it in some experiments on real pianos!!!! (Oh my, use Yamaha parts on something other than a Yamaha?!!!!!! Sacrilege!!!<G>)(I hope they don't get wind of it!<G>) Regards, Best Regards, Joe Garrett, RPT, (Oregon) Captain, Tool Police Squares Are I
